Patent EP-0253612-A3 (EP)
IPC: H04R25/00
Filed: 1987-07-13
Abstract: A hearing aid comprises an automatic gain control 
arrangement (2-6) which provides an output signal of 
substantially constant average level. The arrangement 
has a slow control generator (5) which provides a 
relatively slow release time and adapts the gain to the 
average level of the input signal, and a fast generator 
(4) which provides a relatively fast release time to 
allow impulsive sounds or transient signals to be 
accommodated. When a sufficiently loud impulsive sound 
is received, the fast generator (4) takes control of the 
gain to avoid discomfort or overloading. The 
arrangement (2-6) limits the dynamic range for sound 
pressure levels above a threshold, such as 60 dB SPL.

Title: Liquid dispensing gun
IPC: B05B12/00
Filed: 1988-03-11
Abstract: A gun (10) is provided for repeatedly dispensing 
precisely metered quantities of liquid from a 
pressurized source. The gun includes a valve 
spool (28, 50) axially slidable within a valve 
chamber (21) and having at least first and second

first position that blocks the outlet port (26) of the 
valve chamber (21), while permitting the flow of 
pressurized liquid into a metering chamber (22) of

Title: Sulfur removal by sorbent injection in secondary combustion zones
IPC: F23C99/00
Filed: 1988-07-05
Abstract: Sulfur sorbent and secondary oxidant are added to 
products of combustion passing from a slagging combustor to an 
associated heat-utilization equipment to form a reaction stream 
at a temperature from 1600°F to 2300°F where sulfur is captured 
by reaction with an alkaline earth metal containing sulfur 
sorbent, such as pulverized limestone. Combustion stoichiometry 
in the end use apparatus is between 1.1 and 1.3, at an effective 
calcium-to-sulfur molar ratio of from about 2 to about 5. 
Combustion conditions within the slagging combustor are regulated 
to produce a stream of fuel rich gaseous products, minimize 
formation of NO x  and separately remove most of the fuel's non-­
combustible minerals. This hot gas clean up, prior to combining 
the gaseous products with sulfur sorbent and supplementary 
oxidizer, significantly enhances removal of sulfur constituents 
before the gaseous products pass from the heat-utilization 
equipment into the atmosphere.

Title: Integral thin film injection system for thermal ink jet heads and methods of operation
IPC: B41J2/14
Filed: 1988-11-10
Abstract: A novel thermal ink jet printhead and related methods 
of operation are described. Methods of manufacture of 
the printhead wherein multiple heater resistors (18,20) 
are connected in series between a source of ink supply 
(10) and an output ink ejection orifice (24). A primary 
heater resistor (20) is located in an ink ejection 
chamber (16) and adjacent an output ink ejection 
orifice (24). This resistor (20) propels ink away from 
the printhead, whereas another heater resistor (18) (or 
resistors) is removed from the primary heater resistor 
(20) and is located in an adjacent ink injection 
chamber (14), and is operative to inject ink toward the 
primary heater resistor (20). In this manner, ink 
ejection operational frequency is increased and 
cavitational wear on the heater resistors (20) is 
minimized. Simultaneously, hydrodynamic back pressure 
in the ink ejection chamber (16) is reduced, and control 
over ink drop size and viscosity is improved.

Patent EP-0331245-A3 (EP)
IPC: H01L23/04
Filed: 1989-02-22
Abstract: An integrated circuit (IC) chap package is formed by 
extending the overall dimensions of a standard IC on a 
semiconductor substrate, typically a first silicon wafer, to 
provide an integral band of semiconductor material 
therearound on which are formed a series of spaced IC chip 
input/output pad area extending along the band. A bottom 
peripheral edge of a discrete cap of the same semiconductor 
material, e.g. silicon, is sealingly affixed around an inner 
periphery of the band inboard of the series of pad areas and 
outboard of the IC active circuit areas, so that the cap 
interior spacedly covers the active circuit area and the 
input/output pad areas are exposed. The caps may be made by 
photolithography and microetching techniques from a second 
semiconductor wafer of the same type as the IC wafer. 
Metallization extends on the first wafer from connect pads 
on the active circuit area to the extended and exposed 
input/output pad areas exterior of the cap. The IC may be 
probed for test purposes prior to capping. Use of lead 
frames, plastic encapsulation processes and a ceramic 
housing are avoided, while maximizing the use of compatible 
materials having the same coefficient of thermal expansion. 
In one embodiment, essentially an "all silicon" package is 
provided.

Filed: 1989-03-10
Abstract: In a radio concentrator system, a master station and a terminal 
station cooperate with each to establish connections between remote 
subscriber terminals and a public switched network through radio message 
channels. An intraoffice call is set up 
between first and second subscriber (CT-1, CT-2) 
terminals through the connections (50,60,53,63) 
established in the terminals and master 
stations via the network. Upon establishment of such an intraoffice call, 
the terminal and master stations clear 
their connections (50,60,53,63) and reestablishes 
local connections (54,64,55,65) in the terminal 
station between the subscriber terminals.  
The master station transmits a polling signal at periodic intervals to the 
termination station, which responds to it by transmitting an 
acknowledgment signal as long as the local call is in progress. The master 
station detects if the acknowledgment signal is received in response to the 
polling signal. End-of-call indication is given to the network when the 
response is not received for a prescribed time interval to stop the tariff 
charges on the calling party.
